What software do I need to copy a DVD?

OK, I need to copy this. Normally I use handbreak to rip and idvd to burn. But I don't want to degrade the quality. Some important people need a copy of this. When I use mac the ripper, It rips and now I need to burn it. So I burn the two folders using the os but it won't play.

What software do I need for a full rip and good burn as a playable dvd?
